Definitions

  • the invention relates to a connecting element according to the preamble of claim 1.
  • the WO 2008/058625 A1 discloses a connecting element for producing a form-fitting connection with at least one component, this entering into a friction-welded connection with a second plate in order to fix a first plate between the head of the connecting element and the second plate.
  • the connecting element has a connecting body which has a hollow cylindrical shaft with a cutting edge in order to penetrate the retaining component under rotation and pressure.
  • This type of configuration has the disadvantage that, particularly when connecting fiber-reinforced plastics, chips that arise during the penetration process contaminate the friction weld on the second plate.
  • the object of the invention is to provide a connecting element and a fastening element that enable a component connection of a connecting element and a fastening element and at least one component, in particular a fiber-reinforced plastic component, which is held in a form-fitting manner between the connecting element and the fastening element, in an improved manner.
  • the object for the connecting element is achieved by the characterizing features of claim 1 in conjunction with the features of the preamble.
  • a connection element for a form-fitting connection with at least one component using a fastening element with which the connection element enters into a friction-welded connection has, in a known manner, a head with a drive and a shaft.
  • the shaft has at least two cutting structures on its end face, the cutting structures having cutting edges which lie in a cutting plane.
  • the shaft is delimited on its front side by the cutting plane.
  • the cutting structures are spaced from one another in the circumferential direction and define a cutting diameter which is introduced into a component when the connecting element is rotated.
  • the shank has a region with a cross section which in the circumferential direction between the cutting structures has a reduced extent compared to the cutting diameter.
  • the area of reduced expansion is therefore in a sector of a circle between the sectors defined by the circumferential expansion of the cutting structures.
  • chips produced during the screwing-in process are removed in the axial direction opposite to the driving direction. This ensures that chips can be removed before a friction-welded connection is made, so that they can no longer negatively affect the connection process. If the connecting element is used to connect two fiber-reinforced plastic plates, this also prevents the chips from being pressed in between the plastic plates during the drilling process.
  • the region of reduced expansion preferably extends in the axial direction at least with the length of the cutting diameter from the cutting structure in the direction of the head. In this way, reliable removal of the chips during the drilling process can be guaranteed.
  • the maximum radial expansion of the cutting structure in the cutting plane can be a maximum of 25%, in particular a maximum of 20%, of the cutting diameter.
  • the center point of the end face of the shank can be spaced from the cutting plane by up to 50% of the cutting diameter. This creates a sufficiently large free space for the cutting structures to penetrate and, nevertheless, ensures ideal removal of the chips from the component.
  • the shaft has an area with a cross-sectional area of at least 60% of the area defined by the cutting diameter.
  • a maximum of five cutting structures are provided. As a result, even with small cutting diameters, a sufficiently large cutting structure spacing can be ensured, so that even with small cutting diameters, a meaningful area of reduced expansion can be inserted between the cutting structures.
  • the area of reduced expansion can be achieved by making recesses, in particular in the form of grooves, in a cylindrical shaft with the cutting diameter.
  • the shaft itself can also have a polygonal cross section, the cutting structures then being arranged in the corner regions, whereby the outer circle of the polygon corresponds to the cutting diameter.
  • the shaft is preferably formed from a solid material.
  • the shaft can have a diameter of less than 2.5 mm. This has the advantage that the matrix of the fiber composite material is damaged as little as possible.
  • the connecting element can advantageously be made thin, for which purpose the shaft length is in particular more than one and a half times the cutting diameter.
  • the area of reduced expansion steadily approaches the cutting diameter in the direction of the head.
  • the cross-sectional connection from the head to a shaft is as large as possible, which allows high torques to be transmitted without the head being twisted off the shaft.
  • a fastening element is provided for a form-fitting connection to at least one component, in that the fastening element enters into a friction-welded connection with a connection element penetrating at least one component.
  • the fastening element has a circumferential edge region for contact with a composite component, the edge region defining a contact plane with its end face.
  • the edge area merges into a storage area in the inward direction, the storage area being spaced apart in the normal direction to the bearing plane.
  • the fastening element has a welding area inside the storage area. The welding area is raised in relation to the storage area in the direction of the contact plane, the welding area being at a distance from the contact plane and thus not reaching as far as the contact plane.
  • Such a configuration of the fastening element has the advantage that, in the event that the connecting element, which cuts through at least one component, chips falling out of the lowest layer can be carried away from the welding area into the storage area. This considerably improves the quality of the welded connection between the connecting element and the fastening element, since disruptive chips are removed from the weld area.
  • the storage area is designed to be circumferential and in this way completely encloses the welding area.
  • chips hitting the welding area can be carried away in all directions. This has an effect in particular on the chips subjected to centrifugal force.
  • the fastening element has a rotation lock, which makes it possible to hold the fastening element in the direction of rotation.
  • This rotation lock is preferably designed in the form of a conventional screw drive, in particular an external drive, such as a hexagonal drive.
  • Such a design can also be used to exert, if necessary, a torque on the fastening element which is opposite to a rotation exerted on the connecting element, in order in this way to shear off the integral connection To achieve fastener and fastener. In this way, components fastened between the connecting element and the fastening element can be released again.
  • the weld area has a convex, conical or truncated cone-like geometry. The consequence of this is that chip evacuation is made possible out of the welding area. Nevertheless, there is a sufficiently large contact surface for producing a friction-welded connection.
  • the fastening element can preferably be designed to be rotationally symmetrical within its edge area, with the storage area and the welding area in particular being arranged coaxially. This facilitates the manufacture of the fastening element.
  • the area of greatest extent of the welding area can advantageously be greater than 1.5 mm, in particular greater than 2.0 mm. This ensures a sufficiently large weld zone to produce a firm connection between a fastening element and a connecting element. This is particularly the case when the connecting element has a cutting diameter of at most 2.5 mm.
  • the distance between the welding area and the contact plane can be greater than 1.0 mm. This ensures that there is sufficient free volume between the component to be connected and the fastening element to ensure that the chips slide off into the storage area.
  • the radial extent of the storage area can have a diameter of less than 5.0 mm.
  • the edge area is designed in such a way that it forms an undercut for the storage area.
  • a connecting element with its shank formed on the fastening element enters into not only a material connection with the latter, but also a form connection in the axial direction via the undercut.
  • the invention relates to a connection system for connecting several joining layers, in particular layers made of fiber composite plastic, comprising a previously described connecting element and a previously described fastening element, wherein the Connection element can be welded to the fastening element after self-piercing penetration of the joining layers.
  • connection system can preferably be designed in such a way that the diameter of the welding area of the fastening element is 25% larger than the cutting diameter of the connection element.
  • the welding area of the fastening element and the end face of the shaft of the connection element can have a corresponding design.
  • a convex weld area can be matched to a concave end face of the shaft of the connecting element. This ensures a maximum contact surface and a correspondingly rapid heating at the friction weld joint.
  • the invention relates to a component connection comprising at least two joining layers with a connecting element with a head and a shaft, the shaft penetrating the joining layers in a driving direction and producing a friction weld connection with a fastening element, the fastening element on the side facing away from the head of the connecting element Joint layer rests and forms a cavity with this, in which chips of at least one joint layer are enclosed, the joint layers being held together in a form-fitting manner between the head and the fastening element.
  • the joining layers made in particular of fiber composite plastic can be connected firmly and with little damage to the fiber structure between the connecting element and the fastening element.

  • the introduction of the fillets 16, 20 also allows the cutting structures 18 lying on the end face of the shaft 14 to be created in one work step.
  • a recess is provided between the cutting edges. This recess leads to a spacing of the center point of the shank end from the cutting plane Es of about half the cutting diameter Ds. This ensures reliable penetration of the cutting edges 18 into the fastening structure.
